Metamaterial lens applicator for microwave hyperthermia of breast cancer.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
Artificial left-handed metamaterial (LHM) provides a new perspective for microwave hyperthermia. Four flat LHM slab lenses can be used to form a focus-flexible applicator for breast tumour hyperthermia. By adjusting microwave sources behind the four flat LHM lenses, microwaves emitted from the
Conformal hyperthermia of superficial tumor with left-handed metamaterial lens applicator.

With proper source spacing, low loss left-handed metamaterial (LHM) lens should be useful for hyperthermia treatment of large area tumors. With a flat LHM lens applicator, conformal hyperthermia can be performed by joint heating of multiple microwave sources (antennas). In the hyperthermia, we

To attain deep and localized heating for hyperthermic treatment of cancers, metal plate lens applicators that can converge microwave electromagnetic (EM) energy in the lossy medium such as human muscle with a computer-controlled heating system have been developed. This paper describes a system
An annular focus ultrasonic lens for local hyperthermia treatment of small tumors.

The clinical efficacy of a microwave (MW) hyperthermia system using an electric-field converging (lens) applicator is evaluated for 42 malignant tumours with a maximum tumour depth of less than 7 cm. The mean of the maximum, average and minimum tumour temperature of the 42 tumours are 44.5, 42.5 and

Protein denaturation has been shown to occur in cells during heat shock and is closely correlated with the cellular responses to hyperthermia; however, little is known about protein denaturation in tissue. This study describes an analysis of endothermic transitions in the hyperthermic region using
